CONTENTS DISCHARGING DEVICE FOR PUMP, DRILL, OR OTHER CYLINDERS- Filed Jan. 19, 1928 INVENTOR Patented Jan. 7, 1930 PATENT OFFICE ELGAN S. SIJOAN, F 'SHIPPENVILLE, ,PENNSYLVANIA CONTENTS DISCHARGING'DEVICE'FOR PUMP,,,DRILL, OR OTHER CYLINDERS Applicationafiled. January 19, 1928. Serial No. 247,925.

This invention relates to devices or constructions providing for the discharge of the contentsof pump,- drill or'other contents-retaining cylinders that are removed or being removed from a well bore, andrelat-es-more particularly to supporting means forsuch cylinders of 5a novel and advantageous constructionavhitzh maybe conveniently mounted on "the derrick floor or other suitable suplo port convenient to the operator.

In the drilling ofwells, it is necessary 'to providefacilities for cutting into and breaking up material-at the bottom of the borerand for confining the loose materialso that it may 1 be withdrawn fron1-the--well boreand discharged. The pump or drill cylinders which are utilized 'forthis purposewusually have a valve inlet at their lower-ends for both liquid and solids orsemi-solids, and a valved outlet at their upper ends through which liquid -maypass untilthe spacewithin' the cylinder is practically filled with loose-material, such .assand, pulverized-rock,etc., at which time the cylinder vis-withdrawn from the well bore i and its contents removed. Such a pump cylinder forms the subject matter of my, prior {Patent No. 1,656,798 granted January 7 l7, v1928,-a1id will be-describedand shown in con- ;nectionwit-h. the device .of the present inven-' tion to illustrate its application. *Whilepartioularly designed for pump cylinders of this character, the present inventionis, however, susceptible of use generally as a discharging I support. for contents-retaining cylinders, and consistsin the combinations and constructions hereinafter pointed out and thereafter defined in the claims.

In the accompanying drawings illustrating a preferable embodimentof'the invention and forming; part hereof,

Figure 1 is:a vertical sectional View ofthe support mounting the combined drilling-and pumping cylinder of my patent aforesaid, with its lower valved inlet dropped with its plunger to discharge the contents trapped in the cylinder,

Figure 2 is a horizontal sectional View on the line '22 of Figure 1,

' Figure 3 is a perspective detail ofthe cylinder seating support and discharge tube.

Referring to the drawings by numerals, 1 indicates a base having external edge flanges 2 adapted to overlap and be suitably bolted to the edges outlining an opening in a suit- .with an upwardly inclined flange 5, with its edge concaved'to form anannular tube seat 6.

A tubular member 7 constituting a cylinder support and discharge funnel is mounted upon the annular seat 6, by means of an outwardly flaring external flange 8 intermediate of its ends, this'flange having a diameter to seat .on the support flange and having a convexed-edge 9 contoured to lit the concave of the seat 6.

The interior of the member 7 at a point substantially midway of the tube is formed with an annular flange 10, whose annular horizontal face 11 forms a seat and support for the lower end 'of the pump, drill, etc, cylinder whose contents are to be discharged.

The interior walls of the tube above-and below the seat flange 11 taper'or flare outwardly in opposite directions, the lower taper 12 serving as a discharge funnel and as a guideto assist the contents discharging instrumentalities to return back into the cylinder. The upper tapered portion 13, while preferably upwardly and outwardly tapered as a means'for guiding the lower edge of the drill or pump cylinder to rest onthe flat horizontal seat 11," does not require the same degree of taper as the discharge funnel 12 since it is desirable that the lower edge of the pump or drill cylinder-rests upon the flat annular seat 11. thereby positioning the axis of its bore in alinement with the axis of'the discharge funnel.

The device of the present invention, while particularly desirable for use in connection with combined drill and pump cylinders of the type shown and described in my prior patent aforesaid, is as previously stated, adaptable for use in connection with other 4U I cated for this purpose.

types of cylinders providing means for discharging their accumulated contents. In the drawings, in Figure 1, I have shown a cylinder 14 of the type of my prior patent aforesaid, housing an operating rod 15 for a combined drill head and piston 16 having bores 17 therein covered by flap valves 18 permitting sand, silt, etc. to enter, but ricap valve 19 at the upper end of the cylinder or pump barrel 14 provides means by which liquid may pass up through the upper part of the barrel.

It will be obvious in'the use of the described invention, the lower end of a pump or drill cylinder 14 is inserted in the upper end of the tubular member 7 with its lower of sand, etc., and because of its nature, may

tion of its contents remaining after the pis-v ton head has been lowered. Upon the return movement of the piston to close the valve, the outwardlyflaring sides of the funnel portion 12 will center the piston relatively to'the barrel and guide it back into proper position therein. A device as described provides an expeditious way for cleaning the barrels of their accumulation be readily incorporated in the derrick flooring. where it is most conveniently lo- WVhile the invention has been illustrated as incorporated in a specific form having a special relation to. the pump and drill barrel of my patent aiore-- said, it is to be understood that this specific form is illustrative rather than restrictive; that it may be combined in use with contents providing contentsretaining means which may be lowered below the seated end of the cylinder to permit gravity discharge of the cylinder contents; and thatvariousmodifications and adaptations of the invention will be permissible within its scope and that K of the appended claims.

What I claim and desire to secure by Letters Patent is:

1. A device of the character described comprising a base having its edge formed to overlie the edges of an opening in a stationary support and having an aperture therein edged by a supporting flange, and a member of tubular formation and having an external supporting flange of a diameter to overlie and rest upon the edge flange of said base aperture, said tubular member extending aperture in the base plate and flaring outwardly and being provided with an internal annular flange forming a cylinder seat above its lower end.

2. A device of the character described having an apertured stationary base plate provided with an elevated supporting flange edging its aperture formed with a concaved seat and with a lateral slot extending inwardly from its edge to said aperture, and a member of tubular. formation having a diameter permitting its insertion through said lateral slot and provided with an external upwardly tapering annular flange of a diameter to overlie said supporting flange and formed with a correspondingly convexed seat engaging surface, said tubular member having an internal annular cylinder seat positioned at a point above its lower end.

3. A device of the character described having in combination a base plate having its edgesvformed to overlie the edges of an opening in a stationary support and provided with an aperture therein edged by a supporting flange, said'base plate having a lateral slot extending inwardly from one edge providing an entrance to said aperture, and a tubular member having an external flange thereon of a diameter to overlie and rest upon said edging flange and having below said flange a diameter insertible through said lateral slot, said tubular member being formed with an internal annular cylinder supporting shelf above its lower end.
